Hallo, 
ich habe eine sehr gute Webcam und einen sehr guten Bildschirm (Hardware ist auch top) Zusätzlich habe ich die Videoqualität auf HD eingestellt. Trotzdem ist die Videoqualität im Vollbild pixelig und schlecht. Ich möchte die Meetings aufzeichnen. Doch die Bildqualität ist echt schlecht und in der Aufzeichnung sehr unansehnlich. Wie kann ich die Bildqualität von Zoom noch verbessern? 
Vielen Dank für hilfreiche Tipps und Ideen.  

We are connected to zoom via hubspot. and meetings are scheduled through HUbspot into Zoom. It has worked fine for years. But all of a sudden some of our meeting emails (the automatic ones sent once raised) are missing the zoom link. It seems to be sometimes the link is there and other times it is blank.

Screen shot showing where link should be.

Like i said sometime it happens sometimes it doesn't, so i have ruled out a setting issue

I am using Zoom Workplace 6.2.6 in Ubuntu/ Fedora. My client connects from a Windows laptop.
When I edit some documents through Screen share by controlling their screen. My keyboard shortcuts are not working like ctrl + c, ctrl +v , ctrl +x or ctrl + s.

But these shortcuts are working when i connect from Windows to windows.

I have downloaded the .deb package from Zoom website. Am not using snap version

In Zoom meeting
From Participant's account, he/she  clicked  "Join Session" or "Join meeting" or meeting link before the scheduled time but showing that the meeting has not started.
but when checked with host, 
he joined the meeting.

they were not able to connect on Zoom when both the participant and coach joined the session.
any suggestions?
